MULE FOR SPINNING.

SPECIFICATION forming part of Letters Patent No. 331,368, dated December, 1, 1885.

Application filed March 7, 1884; Serial No. 123,450. (No model.)

To aZZ whom it may concern.-

Be it known that I, EBEN A. BALDWIN, of North Andover, county of Essex, and State of Massachusetts, have invented an Improvement in Mules for Spinning, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention in mules consists in a novel drawing-out scroll, whereby the speed of the carriage may be changed after stopping the movement of the rolls. This invention also consists in improvements in mechanism whereby the relative positions of both the drawing-out and the drawing-in scrolls may be changed with relation to the carriage, as will be described, to vary its speed at the proper points.

Referring to the drawing-out or draft scroll used to give motion to the carriage away from the usual draft-rolls, I have provided it with means whereby that part of the said scroll which by its shape controls the outward movement of the carriage after the movement of rolls has ceased may be varied to adapt the mule to spin different kinds of stock.

In spinning it is necessary to move the carriage at acertain speed with relation to the rolls so long as the latter are in motion, and to vary the duration of the movement of the rolls during the outward run of the carriage, and to thereafter gradually reduce the speed of the carriage until it arrives at its farthest outward point, the final outward movement being slow and nearly even.

Figure 1 is a plan view of a sufficient portion of a mule to illustrate my improvement; Fig. 2, a vertical section of Fig. 1, taken on the line a: m,- Fig. 3, a detail showing in elevation the shaft which carries drums and gear, to be described, the two latter being in section; Fig. 4, on an enlarged scale, shows that side of the drawing-out scroll to which the drawingout rope is to be attached; Fig. 5, a view of the opposite side, to receive the check-rope; Fig. 6, a view of the drawing-out rope side of the drawing-out scroll, it having applied to it a modified form of wing. Fig. 7 shows the opposite side of the scroll similarly modified, and Fig. Sis a cross-section on the dotted line as of the scroll shown in Fig. 4.

In the drawings I have shown but part of the head-stock A; but it and the carriage A, the drawing-in scrolls G, the check-rope scroll D, and the shaft 0 are as common in other mulesas. for instance, in United States Patout No. 272,401, granted to me February 20, 1883, to which reference may be had.

My improved drawing-out scroll B is composed of a central part or disk, 6, keyed to the shaft B; and to opposite sides of the said disk, by suitable screws, 16, are removably attached conical plates b b, the same being loose on the said shaft, the one I) being at that side of the scroll which operates the drawing-out rope E while the one I)" is at that side thereof which operates the checkrope E These conical plates at their apices have tips provided with helical grooves to receive the ropes in usual manner. The can riage being out, the drawing-out rope E will occupy the position Figs. 1 and 2, wherein it will be seen that the said drawing out rope is connected with the disk I) at the point 17, and extended once and a half about the said disk. The said rope is also carried about the wing b thence about the tip b* and the sheave 8, after which the other end of the said rope is attached to the drum E, having worm'teeth at its periphery, constitutinga gear, a, and toothed at its side to be engaged by teeth of the drum E, the said drums being substantially the same as the drums designated by like letters in my application N 0. 123,449, filed of even date herewith. The check-rope is fastened to the tip 9, and when the carriage is in at the rolls the said rope will extend about the said tip, the wing b and about the disk I), and from the said disk the said rope will pass over the sheaves 10 12 on the carriage, and the other end of the said rope will be attachedfco the drum E of the drums E E. The drums E E are loose on the shaft H, which latter is held at its ends in suitable bearings, pZon the carriage A,and by intermediate bearing 18, which latter also serves as an abutment for the spring ll, which,

as in the said application, keeps the two drums together. The wings I) and b are necessary to complete the scroll, and each wing is suitably grooved at its edge to receive its rope. While the rolls are in motion the rope E is in the grooves of the disk part b of the draw- .ing-out scroll, but as soon as the rolls are stopped the said rope rests upon and the outward movement of the carriage is controlled by the wing b To adapt the carriage to commence its slow movement at the desired point during its outward run after the rolls have been stopped, I have made the wing b so that it may be removed from the conical plate b and have another wing of different curvature and length substituted for it.

Any desired number of these wings may be employed, according to the work to be done and the stock being used, and the inner end of each Wing 19 will abut against a shoulder, 20, located at the base of the tip 11*, while the inner end of wing 11 will abut against shoulder 21.

Fig. 6 shows a different wing, b adapted to check the speed of the carriage during a less part of its outward run than the wing, b shown in Fig. 4. The wings I) (see Figs. 5 and 7) are also separate from the conical plate I), so that a wing of greater or less curvature or length may be employed to properly control the check-rope E. When a wing of one length is to be removed and a wing of another length is to be used in place of it, the conicah plate will also be loosened, for the same screw, 16, is employed to hold the outer end of each wing, and the conical plate, once loosened,will be turned on the shaft B until the outer end of the wing to be used comes in contact with the shoulder 22 of the disk I), when the screw 16 will be again inserted, the conical plate having a suitable number of holes to accommodate different lengths of wings. The shaft H has fast upon it a drum, 12, provided with a worm-gear, 40, and near its ends it has fast upon it two clutch-plates, p 1), having teeth adapted to engage with teeth at the inner sides of two drums, p 19, also provided with clutch-teeth, the said drums and plates being kept pressed together by suitable springs, 19', between the drums and the end bearings, pflfor the said shafts. (See Fig. 1.) The said drums 1) have attached to them in usual manner the drawing-in ropes t, which, at their other ends, are connected with the drawing-in scrolls O on the drawingin shaft G. The carriage has bearing-brackets 24 25, which receive two handled shafts, 0 a provided, respectively, with worms 0 and m. The worm m engages the worm-gear a of the drums E E, as in my said application. By moving the said shaft a the drums E E may be turned to wind and unwind either of the two ropes connected with it to change the position of the drawing-out scroll with relation to the carriage, in order to vary the speed of movementof the carriagedu'ring the latter part of its outer run. By means of the shaft 0 and worm c acting upon the wormgear 40, the drum n, to which the outer end of the drawing-in check-rope n is attached, may be turned, turning with it the shaft H and the plates 1), which, by their engagement with the clutching-drums 10, move the latter, causing them to wind or unwind the drawingin ropes i t, and turn the drawing-in shaft 0 and its attached drawing-in and check rolls G and D, to thus adjust the speed of the inward movement of the carriage so that the latter shall not strike in too hard at the headstock. The described change effected by the shaft 0 and its worm is needed according to the speed of the main shafting in the mill where the mule is being used, which speed is frequently varied at different times of the day,according to the number of different machines being driven by the said main shafting. The screws 16 secure together the wings, the conical plates, and the disk I), while the screws 28 merely act to fasten the inner ends of the wings to the conical plate.

I claim- 1. A drawing-out scroll composed, essentially, of a central disk and two independent side plates attached thereto, and provided each with a detachable wing, to operate substantially as described.

2. The central disk grooved at "its periphery for the reception of a rope and provided with shoulders '22, and the two independent plates attached thereto and provided with grooved tips, combined with the detachable wings, to operate substantially as described.

3. The drawing-out scroll and shaft to support it, and the ropes E E attached to the said scroll, and the carriage and the drums E E, each provided with clutch-teeth, and the drum E with aworm-gear, combined with a worm and its operating-shaft, to rotate the said drums and simultaneously take up one and let out the other of the said ropes, substantially as described.

4. The carriage, the drums E E and shaft to support them, and the drawing-out scroll and its shaft, and the ropes E E connected with the drawing-out scroll and with the said drums, combined with mechanism, substantially as described, to rotate the said drums to simultaneously wind and unwind the said ropes, as and for the purposes set forth.

5. The drawing-in-scroll shaft, its support, its attached scrolls O and D,and the carriage, combined with the drawing-in ropes'i and the drawing-in check-rope a and with the drums p pand n, to receive the outer ends of the said ropes t and a", and with mechanism, substantially as described, to simultaneously take up oneIand let out the other of the said ropes, tochange the relative positions of the said scrolls and carriage,to alter the speed at which the latter arrives in at the head -stock, as described.

In testimony whereof I have signed my name to this specification in the presence of two sub- IO scribing witnesses.
